How Long Do Hydraulic Lines Last? ... 😅

I'd never thought about an Annular Cutter - like this? https://www.amazon.com/dp/B07526Q53V

That does look like it would cut a smoother, more to size hole than a holesaw would. $40 is a tad more expensive. AND, an arbor to hold the cutter is still needed, and most of those are M2 taper. I only found one that was R8 and it was over $100 with coolant system.

I think for his 1-1/4" pin the hole saw was a good idea.

Yes that's it.

The better fit and less slop on the pin fit, the less it will wear.
Maybe that's not an issue on a forging press vs a shop press that will be used at max more.

$40 is quite cheap actually

Hougen would be the pro brand name

Hougen Annular Cutters for Mag Drills, Sheet Metal, Machining and Industrial Applications

No matter your need, Hougen offers annular cutters for your every application. From drilling holes in thin sheet metal to large holes in thick steel plate Hougen has the solution. Hougen Annular cutters are used in magnetic drills, hand-held drills, or machine tool applications.

I just mentioned it for others info.

The 3/4" weldon shank is just a close round fit with setscrews

A 3/4" Endmill holder would fit an R8, but it would take up head room in a mill.
A simple R8 3/4" collet would do it too.

K Ken H> Good stuff sir. I like your points about he usable space and getting off center from the ram.

The different plate thicknesses were put in there to target a die total height of ~2''

I like your idea on the "T-shaped" combo die. I'll have to do that for sure.

1 12345678910 - Good point on the annular cutter! That may have gotten the job done as well. I was thinking if there is any slop in there I have some 0.010'' shim stock that I could line the hole wall with. We'll see when I get the pins.

I may make some like this:

Good video - I like where he mentions under full press the sides of frame move in 'n out a bit. That's some serious pressure. I do like the bottom support on this press - did you note how that is done in video? Looks VERY strong.

 

[J. Keeton]

K Ken H> yes sir. Pretty slick.

I just ordered $170 worth of steel! Damn these prices suck now days.

 

[Ken H>]

Where did you order your steel? Kelly Cupples seems to have about best prices around - a tad better than Admirals and Kelly has the powered steel also.

That chart is USD/ton of steel? If so, we need to order by the ton since that's only around $1/lb vs the $3 or $4/lb (plus shipping) from other sources.

I’m not sure what the index is built off of. The % increase is ridiculous for sure.

I ordered from Metals Depot:

4ft of 1/2x4 flat bar
2ft of 1-1/2x1-1/2 square bar
2ft of 1x1x1/4 angle
2ft of 1-1/4x1-1/4x1/4 angle
2ft of 1-1/2x1-1/2x1/4 angle.

Considering the prices that coal iron works and big blu charges for their die sets… the 170$-ish for this steel doesn’t make me feel that bad.

I should be able to make a few of the dies we talked about above with some left over metal for future dies and projects.

 

[Ken H>]

I agree on making your own dies - they are just too easy to make and commercial dies cost waaay too much money. I checked Metals Depot and they do have some decent prices, and decent shipping costs. When I mentioned Kelly Cupples I was thinking of steel for making Damascus, not structural type for building things.

 

[J. Keeton]

K Ken H> I'm pretty sure this is the "rod method" you were talking about when creating these squaring dies?

 

[Ken H>]

That's it - should support the angle nicely. As thick as that angle is it might be ok without support. If a person could get some 3/8" thick angle I'd think it would be just fine with no other support.

edit: I placed an order for 2X2X3/8" angle which should be here Tuesday. The set I made are only 1-1/2" wide as that's about all my dinky 8 ton press would handle. I plan this set to be about 3" wide, maybe 4" and if the press doesn't handle that long it will be easy to cut them off to 3". I'll try these without any support inside the angle since the sides are 3/8" thick. I plan one set to be 1-1/2" on side, and another set about 1" for smaller stuff, especially squaring up a billet. It seems a 1" billet is about right for twisting.

 

[J. Keeton]

Getting there:


I used some scrap plate to build the "flatting section" of these dies... and some 1.5x1.5 for the "drawing section"

Cylinder should be showing up Monday!

I think that drawing section dies must have some radius to work properly.................not flat as they are .Radius on dies is what elongates the steel.If they are flat I don t think they would work ,they should just compress steel there ....

 

[Ken H>]

I sure wish I had enough room on my press for combo dies like that. I was going to ask about the reason you left the drawing dies flat rather than radius around the top? It seems that most other drawing dies are rounded top.

Here's a set of squaring dies I made with 3/8" angle. The sides are around 1" which is about right for my 1-1/2" square canister. Also works good for squaring up a 1" billet for twisting. I made these 3" long rather than the 1-1/2" long of my first set. 1-1/2" is about all the 8 ton press (3" cylinder at 2250 psi) I got from Coal Iron would handle very well.

 

[J. Keeton]

Just copying Coal Iron works. The flat section is only 1/2'' so I'm sure it will still "draw". It would be easy to radius them though if it's an issue.



Nice looking dies K Ken H>

 

[Ken H>]

I suspect Coal Iron left the top flat due to cost savings, as they said about the 12 ton press, made it into a 9 ton due to "sourcing issues". I do like the rounded top better. Note the drawing dies for the 12 ton press - they are half round. Part of the purpose of drawing dies is to create "action" in the pattern with the contours. The flat section would leave that part flat and missing the action once the billet was drawn and ground.

For drawing only I'm sure the flat top would work ok, but drawing is only one function of drawing dies.

 

[Natlek]

Coal Iron works

No , you don t copy them .Look carefully again , only small part is flat rest is RADIUS.This dies work in same principle like roll mill ..........think about that !
Watch this ..WTF?? Don t give link to video clip ?? Watch that video my friend

Take a look at this view of the Coal Iron Combo die, here it looks rounded, but a very small flat on top?:

[J. Keeton]

I'll give mine a go... Worse case is I take them to the slack belt and knock the corners off.
